I have some butter with sea salt crystals in, which I keep in the bread bin, unrefrigerated.
I have noticed that it seems to be getting wet, with small amounts of what looks like water appearing on the inside of the packet, and on the butter?
Why is this? What is this? and is my butter still safe?

My initial guess was that there may be too much salt for the butter when it is at room temperature. However, 6-10% salt content is considered ideal with respect to curbing bacterial growth, as well as the retention and preserving the integrity of flavor. I highly doubt that your butter is salted to such a high degree that it would actually
Lacking further information, here are a few explanations
Did you perhaps buy Mottled Butter;
My guess based on the maount of information you gave about the butter (has sea salt, sweats at room temperature) is not that anyone of these answers is distinctly responsible, but that it is a confluence of the various factors resulting in a mild mottling (perhaps imperceptible to the eye or the palate unless you eat the whole block in one go) that is both attracting moisture from the air, and pressing it out of itself.
I am guessing that if you find the liquid problematic (i.e. does it have a funny taste/smell?) you can put it in the fridge and it will stop sweating/weeping. Otherwise, you run the standard risks of fats and proteins stored with a mild curing at room temperature.
